the volume of a rectangular prism is simply the product of its length, width and height, in this case is just 2 * 6 * 2 ft³.
The answer is 18. Since you’re dealing with a power of 10, and there is 18 digits in that number, you can reach a higher number then the number shown above.
Total number of animals: 40
Types of animals: 4
Adult goats: x
Adult rabbits: 2x
Child goats: 3x
Child rabbits: 2x
x+2x+3x+2x = 40
8x = 40
x = 5
There are 5 adult goats.
The correct answer is 5 adult goats.
Check the picture below.
so the composite is just 2 triangles, one rectangle and one parallelogram.
we know the height and base of the triangles and length and width of the rectangle.
now, the parallelogram, we can simply split in in two triangles and a rectangle, like you see the split in the middle, and that gives us two more triangles and one rectangle.
so, we can simply get the area of each of those figures and sum them up, and that's the area of the composite.
The answer will be
40-50d
